WVILLIAM B. CARRIOK, OF CHICAGO, ILLINOIS.

GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 721,997, dated March 3,1903. Application filed April 28, 1902. Serial No. 104,962. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM B. OAEEIoK, a citizen of the United $tates,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Gas-Burners; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.

This invention relates to gas-burners, and particularly to that classthereof having a pilolli-light supplied by a by-pass through the coo aThe object of the invention is to form a burner of the class describedhaving means whereby the pilot-light will light a plurality of jetssimultaneously.

. The invention is particularly applicable to cluster-lights of theincandescent kind and serves to light all the jets of the cluster atonce.

Generally speaking, the invention consists of a burner located adjacenta cluster of lights, which burner is provided with a pilot-light and hasseveral nipples 0r openings which project flame in all directionslaterally, so as to ignite the main jets surrounding said burner.

In the accompanying drawings,'Figure 1 is an elevation of the device, acluster of burners surrounding the same being indicated in dotted lines.vention detached, part of an inclosing tube being broken away. Fig. 3 isa cross-section on the line 3 3.

Referring specifically to the drawings, 6 indicates the valve-casing,which is screwed to to a T in the main supply-pipe 15. The casingcontains a cock 7, which, in addition to the main passage, has a by-passcommon in constructions of this character. The main passage communicateswith a pipe 8 and the by-pass with a small pipe 9. The upper end of thepipe 8 is provided with a number of lateral discharge nipples oropenings 8 and with a spreader 8 above the same. The pipe is Fig. 2 isan elevation of my in-' extended high enough, when used in connectionwith a cluster of lights having chimneys, (indicated. at 14,) to bringit above the tops of the chimneys. The small pipe 9 supplies thepilot-light at the top thereof, which is inclosed by the usual micachimney, (indicated at 10.) One arm of the cock has a pull-chain 11, andthe other arm has an opposing spring 12. A chain 11 may be convenientlyattached to the main shut-off chain in case such be used.

In operation when the chain is pulled, the gas to the main lights 14being turned on, the main passage of the cock is opened and the gasflowing from the nipples is lighted by the pilot-light. The direction ofthe nipples and the action of the spreader cause the flame to beprojected laterally across the tops of the chimneys of the cluster,thereby igniting the burners thereof. When the chain is released, thespring closes the main passage and opens the by-pass, igniting thepilot-light and extinguishing the burner.

It will be seen that by this construction a cluster of lights may belighted from one pilotlight.

An inclosing tube is indicated at 13, surrounding the pipes 8 and 9 andacting to protect the same and to support the mica chimney.

What I claim is- 1. The combination with a cluster of burners,of alighting attachment therefor comprising an independent burner havingmeans to spread the flame laterally in various directions, and anindependent pilot-light for the burner.

2. The combination with a cluster of burners, ofan independentburner-tube projecting above the burners, laterally-directed jetnipplesat the top of said tube, a pilot-light adjacent the nipples, and a valvecontrolling the flow of gas to the burner-tube and pilotlight.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM B. OARRICK.
